Wilwood Mustang II, Pinto and Bobcat Plain-Rotor Front Brake Conversion, Red Dynalite Calipers, 5x5.00-Inch Wheels

This Wilwood Dynalite kit is a front conversion with 5 x 5.00-inch hubs for Mustang II, Pinto and Bobcat Disc Spindles. Four-piston Dynalite Internal calipers and 12.19-inch rotors combine with aluminum hubs drilled for 5 x 5.00-inch wheels. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering develops disc brake systems for motorsport, street-performance and specialized applications. Its calipers, rotors, master cylinders, valves, fittings and brake lines must be selected as parts of a complete, matched braking system.

Technical Details

• Manufacturer part number: 140-14530-R.
• The specified lug caliper is a Dynalite. It combines a Red Powder Coat forged aluminum body with 4 pistons per unit; the published piston material is stainless.
• Bores and friction material: 1.75, 1.75 inches, with BP-10 pads supplied for the specified calipers.
• The vented discs have plain face friction surfaces and Iron construction. Nominal dimensions are 0.81 in; 20.57 mm through the braking section and 12.19 in; 309.63 mm at the outside edge.
• Included wheel hubs use aluminum construction and the listed threaded-stud arrangement. They are separate from the friction discs.
• The wheel-stud thread is 1/2-20; the matching wheel mounting pattern(s) are 5 x 5 in; 5 x 127 mm. These describe different aspects of the attachment.
• When planning the line connection, account for the 1/8-27 NPT caliper inlet.
• The supplied hardware mounts the specified brake package. It does not include replacement spindles, a brake booster or a master cylinder.
• The caliper package calls for at least the published 15 in; 381 mm wheel diameter, plus sufficient spoke and inner-barrel clearance.
• Flexlines are excluded from the brake package. Select the chassis-specific hoses and confirm safe clearance throughout travel. Separate reference: 220-8307.
• This is a kit listing; one package contains the brake components described above.

Fitment & Compatibility

Use the listed 1974–1978 Mustang II, 1974–1980 Pinto and 1975–1980 Bobcat original disc spindles. The supplied 5 x 5.00-inch lug pattern must match the wheels; it is not the original four-lug pattern. Stamped-steel wheels require separately ordered hub shield 300-10716. Master-cylinder pushrod changes may be required for a separately planned master conversion. Models covered: Mustang II, Pinto and Bobcat. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.

Kit fits 74-80 Pinto / Mustang II original disc brake spindles only.

Kit may fit some 15" wheels. Check wheel clearance diagram in kit installation instructions before purchase.

Separate universal hose choices are 220-7056 (14-inch), 220-7699 (16-inch) or 220-8307 (18-inch). Select the correct length and end fittings; these are alternatives, not three required kits.

Master Cylinder may require modification to existing pushrod assembly to install.

If a separate rear parking-brake conversion is also planned, a universal parking cable may need cable or vehicle changes; it is not part of this front kit.

PMB Performance has more than 20 years of experience with parts and fitment. We can help review the specified kit against your vehicle's actual spindle, axle or existing brake components and wheel-clearance information.
